REGISTER DEVICE FOR FEEDER S.

1710 all ii /tom it may concern V Be it known'that I, hum B. S'roR'r, :1 citizen of the United States, residing in the borough of Brooklyn, county of rings, city "and State of. New York, have invented a certain. new and useful Register Device for Feeders, of which the following is a specification. Y Q i This invention relatesv to machines for *feeding sheets to a printing couple, to a folder, or for feeding insert sheets or covers to the folder of a web printing machine.

The'objects of the present invention are the same as there set forth in the specification of my application for patent, filed March; 12, 1912 and. numbered serially 683,330, but are accomplished 'by means of 7 a different arrangement of mechanism. t

Fig. 10 is a plan view of a portion of the device illustrated in Fig. 8. Fig. 11 isa diagrammatic ricw of a modification.

In all of the views, like parts are desighated by the samc referencicharacters.

Referring particularly to Figs. 1 to 8 inclusive, the feed rollers 1, 1 are rotated by suitable mechanisni, at normal speed. These rollers are adapted to have the sheets fed to them from any form of feeding device, such as a pile feeder or continuous feeder.

The feeding devices similar to that shown in my con-whaling application, before identified, may be employed in feeding the sheets to the feed rollers 1, 1. From the feed n'illersthc sheets pass upon the tapes 2 betweeufl the upper gage roller 3 and lower gage roller 4. From those gage rollers, they pass-between the food table rollers 5, 5, which are rotated at normal speed and then pass from the table 6, so as to be fed between the rolls of the printing coup-lo. Re-

ferring more particularly to Figs. 1 and 2,,

the table'6 has edge guides 7 7 for controlling and defining the edge of the sheet. These guides are carried, by suitable supports 8 from the frame 9, of the machine. The continuously operated driving shaft 10 drives the shaft for the feed rollers 1, 1, and feed table rollers 5, 5 by means of bevel gears. The lower gage roller 4 turns with the shaft 11. This roller is divided intoas many sections as are necessary. A lay shaft 12 is arranged parallel with the shaft 11. For the purpose ofrotating the gage rollers, I provide mechanism which comprises a spur gear 13, which is loosely mounted. upon the shaft 11. This spur gear meshes with and is,

shafts which support the feed table rollers 5, 5, which in turn is driven by the bevel gear from the shaft 10, as shown. The connections between the shaft 11 and spur gear 13 are as follows: A toothed sector 15 is fixed upon the shaft 11, and turns with the latter. A sccond'toothcd sector 16 is in engagement with the toothed sector 15, and is carried upon a short shaft 17. This short shaft is supportcdlin bearingsin the spur gear 13, and rotates with the latter. The shaft carries a crank 18 on the other side of the spur gear fromthe toothed sector. ()n the end of the crank is a pin 19, which may be hushed with a" roller, as shown, for rcductin'g friction. This pin engages with a .cam 20, which surrounds the shaft 11. The

cam is supported concentrically.inrelation to the shaft by being carried upon a bushing 21, attached to the frame 9. The cam 20 is formed of two partsan accelerating cam part 22, anda retarding cam part 23; each being shown in Figs. 6 and 7, respectively. The retarding cam part 23 is attached fixodly to the frame 9. The accelerating cam part is capable ofrotary motion in respect to the bushing. Its position is determined by means of mechanism which includes worm teeth 24 on the cam part, and a Worm 25 carried bythe frame and engaging with the worm teeth. A hand wheel 26 gives motion to the worm, and allows a limited but sufiicient rotary movement of the accelerating cam part. The lower ga e roller has a high part 27, extending a su cient distance to propel the sheet to two rollers 5, 5, and a low part 28 extending through the rethrough the agency of the spur gears 13,

the lay shaft 17 and the toothed sectors. If the cam 20 were in the form of a circular groove concentrically located in relation to the shaft 11, the shaft 17 would not be oscillated in its bearings by engagement with the crank pin with the cam. As, h0wever,

thecam slot is distorted, asshown, the pin following this cam slot will oscillate the shaft 17' to an extent which depends upon the shape of the slot and the position that the pin occupies in the cam. When the pin engages with the low part of the cam, the shaft is oscillated in one direction, andwith it the two toothed sectors are relatively moved, which'hasthe effect of turning the shaft 11 slightly in advance of the spur gear 13. When the pin is in the high part of the cam, it has the reverse efl'ect and slightly retards it. The shape of the cam is such that when the gage 29 is rising through the opening of the table, and is about to engage with the sheet which is being fed forward by the tapes, itj-will begin to be re tarded. As the sheet is being fed forward atnormal speed by means of the tapes, the retardation of the movement of the gage will bring it into engagement with the forwardedge of the sheet. This retarded movement will continue until the stop-has passed under] the upper gage roller 3, and until the forward edge of the high part 27 of the lower gage roller engages with the sheet and pinches it against the upper-gage roller 4 3. The sheet will then'lfe fed forward by engagement with these two rollers.

While the sheet'is in engagement with the gage and the latter is being retarded, the pin 19 will be in engagementwith the retarding part 23, of the cam. When the high part of the roller is in engagement with the sheet, the pin will have entered the accelerating'part 22 of the cam. The effect of this will be to oscillate the shaft 17, turn the sectors and advance the gage roller relatively to the shaft 11. The efi'ect of this will be to accelerate'the sheet so that its speed will then be equal to normal. This'accelerationwill continue until the sheet is fed-sufficiently far so that it will be'g'ripped between'the' feed table'rollers 5, 5." The operator, ,by adjust- 'ing the position of the hand wheel 26, can

displace the accelerating cam part 22 in rethe same e eat as the retardation of the gage .ated and the gage will beretarded.

lation to the retarding cam part 23, as shown I in Fig. 5. The effect of this will be to continue the acceleration for a' longer period than when the cam parts are arranged, as

will be decreased and the total movement of the sheet will be below normal.

From the foregoing description, it will be apparent that I attain the same objects by the double cam'that I do by the two-cam arrangement described in my co-pending ap plication before referred to.

Fig. 8 illustrates a modification of the inyention in which the gage 29,;instead of be ng supported upon the gage; roller, is supported upon the tapes 2. Inthis view is shown a spur gear 30,on the shaft 11, for rotating the gage roller, and this spur gear engages with an intermediate spur gear 31, which in turn, is rotated by the spur gear 13. Fig. 8 shows a convenient way of grouping the parts, the spur gear 31 being mounted upon the same shaft which supports the cam 20. This impression cylinder 33, transfer cylinder 34 and delivery cylinder 35 are arranged in the usual manner. According to the apparatus illustrated in Fig. 8, the roller 4; is of such diameter that the type will'make one complete revolution.

for each sheet that is fed. The gage, when supported by flexible carriers, will have its movement retarded in precisely the same manner as the gage 29 which is attached directly to the lower gage roller; In order to avoid any chance of slipping of the tapes upon the roller, the latter may be provided with notches 36, which will be engaged by teeth 37 carried by the tapes.

According to the modification of the inventi'on illustrated in Fig. 11, I employ accelerating rollers 38, which are geared to rotate at a speed above normal. According to this embodiment of the invention, -'thecam. 20 is sh made that it accelerates only and does not retard the movement of the gage rollers while controlling the sheet. The gage, therefore, when engaged by the sheet, moves at normal speed. The sheets are brought into engagement with the gage by acceleratio of the rollers 38,- 38, which has in the devices previously described. i

The acceleration rollers 38 38 may be eniployed in the structure illustrated in Fig.

8, in which event the sheet will. be'acceler- In accordance with the provisions of the.
